Principal focus of convex lens:

The image formed by a convex lens

A beam of light diverges from P on the axis of a convex lens and the after passing through the lens is reflected from the surface of a convex mirror. The reflected beam is brought to a focus by the lens at P itself. (a) Find the focal length of the lens. Given that the distance of the lens and the mirror is 10cm. The distance of P from the mirror is 30cm and the focal length of the mirror is 10cm.

A ray of light is going towards the focus of a convex lens. Draw a ray digram to show the path of this ray of light after refraction through the lens.

Converging light rays are falling on a convex lens. If the focal length of the lens is 30 cm, then find the position of the image.

A convex lens of focal length 1 meter and a concave lens of focal length 0.25 meter are kept 0.75 meter apart. A parallel beam of light first passes throught the convex lens, then through the concave lens and comes to a focus 0.5 m away from the the concave lens.

A convex lens of focal length 1 meter and a concave lens fo focal length 0.25 meter and kept 0.75 meter apart. A parallel beam of light first passes through the ocnvex lens, then through the concave lens and comes to a focus 0.5m away from the concave lens.

If an object is placed at the focus of a convex lens, where is the image formed?
